gcc version 3.4.6 (Gentoo Hardened 3.4.6-r2 p1.5, ssp-3.4.6-1.0, pie-8.7.10)

[Kai Krakow]

Gentoo's bug tracker points here because it seems to be a general problem when compiling with a hardened toolchain.

For me it happens with the following version:

• VirtualBox 1.6.4
• GCC profile: gcc version 3.4.6 (Gentoo Hardened 3.4.6-r2 p1.5, ssp-3.4.6-1.0, pie-8.7.10)
• CHOST = x86_64-pc-linux-gnu
• Linux 2.6.25-hardened-r8 SMP x86_64 Intel(R) Xeon(R) CPU E3110 @ 3.00GHz GenuineIntel GNU/Linux

Any news on this issue?

[Frank Mehnert]

No news. Actually we don't have any problems on any other Linux distribution (Debian, Ubuntu, Fedora, openSUSE, rhel, ...) I would suggest you to switch to a newer compiler, for example gcc-4.2.
